John Gill Commentary Mark 12:3

"And they took him, and beat him, and sent him away empty." — Mark 12:3 (ASV)

And they caught him
This clause is left out in the Syriac and Persic versions, though it seems proper to be retained; and denotes the rudeness and violence with which the prophets of the Lord were used by the Jewish nation:

and beat him :
either with their fists, or with rods, and scourges, till the skin was flayed off:

and sent him away empty ;
without any fruit to carry with him, or give an account of, to the owner of the vineyard.
